Parts and Accessories CUTTING AND INSTALLATION INSTRUCTIONS FOR FLEXIBLE TUBING

FLEXIBLE TUBING CAN TWIST OR UNRAVEL WHEN CUT, CAUSING ITS DIAMETER TO CHANGE AND MAKING INSTALLATION DIFFICULT. THIS OCCURS BECAUSE FLEXIBLE TUBING MUST MAINTAIN FLEXIBILITY IN ORDER TO FUNCTION PROPERLY, AND, THEREOFRE, CANNOT BE TIGHTLY WOUND IN THE MANUFACURING PROCESS. HOWEVER, FLEXIBLE TUBING CAN BE MANAGED FOR TROUBLE-FREE INSTALLATION BY FOLLOWING THESE GUIDELINES.

CUTTING

1. PREPARE PLACE A TACK WELD BETWEEN CONVOLUTIONS ON EACH SIDE OF THE INTENDED CUT TO KEEP ENDS FROM TWISTING OR UNRAVELING. 3. TRIM EACH SIDE OF THE CUT WILL NOW HAVE A SPIRAL “TAIL” THAT MUST BE REMOVED TO THE POINT AT WHICH IT IS ATTACHED. BEND EACH TAIL UNTIL IT BREAKS, OR BEND AND USE CUTTING SHEARS TO REMOVE.

IF A WELDER IS NOT AVAILABLE, INSERT A MANDREL OR BACK-UP PIPE INTO THE TUBING AND PLACE A PUNCH MARK DIRECTLY ON CONVOLUTIONS ON EACH SIDE OF THE INTENDED CUT.

2. CUT PLACE THE TUBING SECURELY IN A VICE. CUT WITH A 4. DEBURR METAL CUTTING BAND SAW OR A HACKSAW WITH 32 DEBURR BOTH CUT SURFACES WITH A HAND- TEETH PER INCH. OPERATED DRUM SANDER OR FILE.

INSTALLATION

FLEXIBLE TUBING’S FUNCTION IS TO PREVENT EXCESSIVE STRESS ON EXHAUST SYSTEM COMPONENTS BY ABSORBING VIBRATION AND THERMAL EXPANSION THAT WOULD OTHERWISE CAUSE SYSTEM COMPONENTS TO SHAKE LOOSE AND BREAK.

TO PROVIDE ADEQUATE FLEXIBILITY, FLEX TUBING SHOULD BE THEN PLACE THE ENTIRE PIECE OF TUBING ON THE INSTALLED IN A HALF EXTENDED STATE. TO REACH HALF TABLE AND PUSH THE END DOWN UNTIL STRAIGHT- EXTENSION, PLACE THE MIDDLE OF THE TUBING OVER THE ENED. THE TUBING IS NOW AT HALF EXTENSION. EDGE OF A WORK BENCH, PUSH DOWN ON BOTH HALVES AND NOTE: DO NOT USE FLEXIBLE TUBING TO FORM AN BEND AS MUCH AS POSSIBLE. EXHAUST PIPE BEND. USE ELBOWS INSTEAD.
